Anthropogenic Disturbance and Population Viability of Woodland Caribou in Ontario [PDF]

, 2020
One of the most challenging tasks in wildlife conservation and management is to clarify how spatial variation in land cover due to anthropogenic disturbance influences wildlife demography and long‐term viability.

The West Central Alberta Woodland Caribou Landscape Plan: Using a Modeling Approach to Develop Alternative Scenarios

Rangifer, 2011
Woodland caribou (Rangifer tarandus) are classified as threatened in Alberta. In support of Canada's Species at Risk Act, a Recovery Plan for Woodland Caribou in Alberta was completed in 2004 which required local implementation plans to be completed ...

Use of island and mainland shorelines by woodland caribou during the nursery period in two northern Ontario parks

Rangifer, 2011
Predation is considered a primary limiting factor of woodland caribou (Rangifer tarandus caribou) populations across North America. Caribou are especially vulnerable to predation during their first few weeks of life and have evolved space-use strategies ...

Canopy, snow, and lichens on woodland caribou range in southeastern Manitoba

Rangifer, 1996
I examined the relationships among snow cover (api), lichen abundance, and canopy composition on the range of the Aikens Lake population of woodland caribou (Rangifer tarandus caribou) in southeastern Manitoba.

An examination of recovery planning for forest-dwelling woodland caribou (Rangifer tarandus caribou) in Ontario, Canada

Rangifer, 2008
Ontario’s population of forest-dwelling woodland caribou is listed both federally and provincially as a species at risk. It is estimated that 20 000 woodland caribou remain in Ontario, of which approximately one quarter inhabit the boreal forest and are ...

Increase in plant productivity in the tundra in Sweden is not related to increasing presence of warm‐adapted vascular plant species

Ecography, EarlyView.
Over the past decades, Arctic and alpine biomes have warmed faster than the global average. Substantial vegetation changes have been reported as a response to this warming, including increased productivity and the spread of warm‐adapted (thermophilic) species that are less resistant to grazing pressure into higher latitudes and altitudes.

Validating antler‐ and movement‐based estimates of caribou reproduction using video camera collars Validation des estimations de la reproduction du caribou basées sur la rétention des bois et  sur le déplacement à l'aide de colliers‐caméras

The Journal of Wildlife Management, EarlyView.
We used GPS video camera collar data from barren‐ground caribou in the Porcupine and Western Arctic herds to validate antler‐ and movement‐based methods for estimating annual reproductive metrics. Antler retention was highly accurate for estimating parturition, but the movement methods we tested performed marginally for estimating parturition and ...

The need for the management of wolves — an open letter

Rangifer, 2007
The Southern Mountain and Boreal Woodland Caribou are facing extinction from increased predation, predominantly wolves (Canis lupus) and coyotes (Canis latrans). These predators are increasing as moose (Alces alces) and deer (Odocoileus spp).
